MCB stands for Miniature Circuit Breaker.

• MCB is an electrical switch that automatically protects an electrical circuit from damage caused by overload or short circuit.

• It is a type of circuit breaker that is commonly used in residential and commercial buildings.

• MCBs are designed to trip and interrupt the flow of electricity when the current exceeds a certain limit.

• They provide protection against electrical faults and pr...read more

LED stands for Light Emitting Diode.

• LED is a semiconductor device that emits light when an electric current is passed through it.

• It is commonly used in lighting fixtures, electronic displays, and indicators.

• LEDs are energy-efficient and have a longer lifespan compared to traditional incandescent bulbs.

• They come in various colors and can be used for decorative purposes as well.

• Examples of LED applications include traffi...read more

HT panel is a high tension electrical panel used for controlling and distributing power to various electrical equipment.

• HT panel stands for High Tension panel

• It is used for controlling and distributing power to various electrical equipment

• It is commonly used in industries and large commercial buildings

• It is designed to handle high voltage and current levels

• It contains various components such as circuit breakers, transf

Current is the flow of electric charge through a conductor.

• Current is measured in amperes (A)

• It is caused by the movement of electrons

• Current can be either direct current (DC) or alternating current (AC)

• Examples of current include the flow of electricity through a wire or the current in a battery

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

• Ohm's law is a fundamental principle in electrical engineering.

• It states that the current flowing through a conductor is directly proportional to the voltage applied across it.

• The proportionality constant is known as the resistance of the conductor.

• Ohm's law can be expressed mathematica...read more
